Convert object direction (rotation) to yaw and pitch

[neilb]

Shiva's got some functions to specify rotations as yaw, pitch and roll, but there's nothing I could find to get an object's rotation as yaw and pitch.

The following will convert the vector returned by object.getDirection() to yaw and pitch.

Code: Select all

    local dx, dy, dz = object.getDirection(application.getCurrentUserActiveCamera, object.kGlobalSpace)
    local yaw = -math.atan2(dx, -dz)
    local pitch = math.atan2(dy, math.sqrt((dx * dx) + (dz * dz)))

Nice snippet!
